Scheduling an agent online

Agenty offers a powerful and flexible scheduling capabilities for your agents to run them automatically on minutes, hourly, daily, weekly basis or any particular day(s) you want to scrape data from websites on a scheduled time and day.

The scheduling feature in Agenty is most interesting to automate the data collection service running on server. And, using the scheduling feature you can configure your scraping agent to run it on fixed interval automatically to refresh the data, for examples here are some use cases:

  • Extract stock price from a website in every 5 minutes and send an email alert when price drop/increases.
  • Extract price from competitor websites every hour and import output to SQL using webhook.
  • Scrape new jobs from jobs portal on Monday, Wednesday and Friday at 10:00am and send to a Google spreadsheet in your account.
  • And lots more…

Note : All the time in scheduler are in UTC - Coordinated Universal Time

Create Schedule

  1. Go to your agent details page, which you want to schedule

  2. Click on top right side Manage this agent button and select the Schedule this agent option as in this screenshot

  3. The scheduler dialog box will open where you can schedule your agent as per your requirement on minutes, hourly, daily, weekly, monthly or yearly basis

  4. In this example, I scheduled my scraping agent on daily basis - So I clicked on Daily tab and selected ‘1’ from days dropdown and select the start time as 8:25 AM to run my agent.

  5. And then click on Save button.

Once, the agent has been scheduled- You can see the scheduling description on Next Scheduled Run option on the agent page.

Note : A particular agent can have only one schedule and each time you click on the “Save” button, the existing schedule will be overwritten if any

CRON Expression

CRON is a UNIX tool that has been very known for its powerful scheduling capabilities. You can use the CRON expression in Agenty to create an advance scheduler for your agent.

For example, we were talking to a web scraping customer last week who want to schedule his web scraping agents on every 15 minutes, between 07:00 AM - 10:59 PM, only on Monday to Saturday which was not possible with scheduling UI. So, we end-up using following expression for him to meet the requirement from back-end:

0 0/15 7-22 ? * MON,TUE,WED,THU,FRI,SAT *

And that gave us a new idea to build a feature for all, and it’s here as of December, 2019 -

Here are some sample CRON expression, and more details about how to create these CRON expressions can be found here.
